Hello all, I am getting an “Unable to Connect to Home Assistant” error screen when using DuckDNS from within LAN.
- Router: OPNSense. GUI is using a non-standard port (not 443)
- DNS: Adguard Home + Unbound as plugins within OPNSense.
- HomeAssistant OS is running NGINX Proxy Manager integration (thanks Frenck!).
- Port forwarding: I am forwarding 80 and 443 to hass_ip. And, in Unbound DNS Overrides, I have my duckdns domain with value of hass_ip (type A). I think this is how to set up a split DNS, right?
If I access hass_ip:8123 from LAN it works.
If I access duckdns from WAN it works.
But, if I access duckdns from LAN it does not work. Interestingly, the URL changes to duckdns.org/lovelace and I get a home assistant icon so it looks like it is making some sort of contact with home assistant…but text under it states: Unable to connect to Home Asssistant.
Additionally, accessing other Proxys set up on NGINGX work from WAN but from LAN thye get me ERR_CONNECTION_TIMED_OUT.
Turning on NAT reflection makes no difference.
Any ideas what is messed up??
